GlcNAcβ(1-4)[Fucα(1-6)]GlcNAc is primarily utilized in glycobiology research to study carbohydrate-protein interactions, particularly in the context of cell signaling and immune responses. It serves as a key structure in understanding the role of glycosylation in cellular processes, such as cell adhesion and pathogen recognition. This compound is also employed in the development of glycan-based biomarkers for diseases, including cancer, where altered glycosylation patterns are often observed. Additionally, it is used in the synthesis of complex glycoconjugates for vaccine development, aiming to enhance immune system targeting of specific pathogens. Its application extends to the study of host-microbe interactions, providing insights into how pathogens exploit host glycans for infection.
